Gemstones are minerals distinguished by rarity, transparency, color and brightness. They are used to make ornaments and jewels; their uniqueness is associated with their aesthetic and optical properties. Gemstones such as quartz, amethyst, agate, tiger’s eye, hematite and jasper in all their color variants are processed and assembled to create large tiles measuring 305x142x2.5 cm.
